Maintenance

Periodic cleaning is necessary in order to guarantee the expected service life of your facade or roof. Every manufacturer prescribes stringent requirements for cleaning frequencies for pre-painted steel or aluminium in order to provide a guarantee on their supplied products. Many end users have no idea of what is happening on their roof or facade. The consequences of contamination are clearly far-reaching. However, we frequently conclude that it is already too late! The factory coatings and surfaces are then damaged to such an extent that, in many cases, a new coating must be applied or even complete cladding systems must be replaced.

Service life of coating

Under normal conditions, aluminium or steel cladding that is equipped with a correct coating, is guaranteed to have a long service life, provided that this cladding is periodically cleaned in the correct manner.

Periodic cleaning

Periodic removal of contamination prevents chemical substances in this contamination from adversely affecting the surfaces. These surfaces are affected by acids, salts and other aggressive substances and this can cause them to age faster. Moreover, thick layers of dirt can absorb and retain more humidity, with this enhancing the aggressiveness on the surface.

Rainfall

In addition to the dirt loading factors, the extent of rainfall from the cladding plays an important role. For example, it is known that cladding underneath overhangs or awnings is more susceptible to damage than cladding that receives rainfall regularly.

Increased risk to the environment

The location of your building also plays a major role in the amount of atmospheric contamination. Buildings that are located in the vicinity of busy roads, heavy industry, coastal areas and forests have an increased risk of contamination. Practice has shown that a good coating, provided that it is periodically cleaned, retains its protective and aesthetic properties for many years.
